Summary: In this study, a mathematical model for machining-path mapping from free-state to clamped-state of thin-walled parts with curved surface was established. The proposed method re-designed the machining-path under the clamped-state to avoid machining error caused by clamping deformation, and the effectiveness of the method was validated through experiments.

Summary: This study developed an adaptive clamp system using phase change material to reduce deformation in the assembly of thin-walled parts. The system adjusts clamping position when the material turns liquid, allowing stress-releasing deformation after rough machining. The use of the system significantly improves the accuracy of thin-walled parts manufacturing.

Summary: Hybrid machining-forming technology combines thin-structural machining and incremental forming processes to manufacture complex geometry parts. While this technology reduces raw material usage, it faces dimensional and geometric inaccuracies due to springback. Research shows that cutting parameters and residual stresses affect springback, with machining feed rate impacting workpiece fracture during the forming stage.

Summary: Wire and arc additive manufacturing (WAAM) technology is gaining popularity due to its high production capacity and flexible deposition strategy. However, surface irregularity is a prominent drawback of WAAM, requiring secondary machining operations. This research determines the most suitable machining strategy by assessing specific cutting energy and local machined volume, and finds that machined volume and specific cutting energy are the main factors affecting the machinability of WAAMed parts. Furthermore, it is shown that hardness should not be used as a criterion for as-built surface processing, and there is no machinability difference between multi- and single-material components for low machined volume and low surface irregularity.

Summary: This paper studied the minimization of the failure probability of machining distortion by controlling the uncertainties of inputs. A fuzzy inference model was proposed to determine the effects of uncertain factors on the machining distortion errors. Comprehensive matching was defined to measure the importance of uncertain inputs to outputs. Two engineering examples were employed to illustrate the accuracy and efficiency of the proposed approach.
